MetaStealer is an information-stealing trojan that emerged in March 2022 as a commercially available malware-as-a-service offering. Marketed by a threat actor under the handle "META" for $125 per month or $1,000 for lifetime access, this stealer was explicitly advertised as having the same core functionality as the notorious RedLine stealer but with claimed improvements. It targets Windows systems and focuses on extracting saved credentials, browser data, cryptocurrency wallets, and other sensitive information that can be sold or used for identity theft and financial fraud.
Despite its claims of superiority over RedLine, MetaStealer operates on familiar principles: silent execution, rapid data harvesting, and exfiltration to attacker-controlled servers. Its commercial availability means it's accessible to low-skill criminals, making it a persistent threat in phishing campaigns, malicious downloads, and software cracks distributed across the internet.

How It Spreads
MetaStealer's commercial nature means it's distributed by a wide range of cybercriminals with varying levels of sophistication. Because buyers can customize deployment methods, we see this stealer arriving through multiple infection vectors. The most common entry points mirror those used by other info-stealers: infected email attachments, fake software downloads, and exploit kits targeting unpatched vulnerabilities.
One particularly effective distribution method involves bundling MetaStealer with pirated software, game cheats, or productivity tools advertised on file-sharing sites and torrent platforms. Users seeking free versions of expensive software unknowingly execute the payload, which silently harvests their data while the "cracked" program may or may not actually function. Another favored vector is malicious advertising (malvertising) that mimics legitimate software update prompts or security warnings, tricking users into downloading and running the trojan.
Common distribution vectors include:
- Phishing emails with malicious attachments disguised as invoices, receipts, or shipping notifications
- Compromised or fake websites offering software cracks, keygens, or "free" premium tools
- Social media links and direct messages promising exclusive content, game cheats, or financial opportunities
- Malvertising campaigns that redirect users to exploit kit landing pages or direct downloads
- Trojanized installers for legitimate-looking applications distributed through third-party download sites
- Search engine poisoning that places malicious download links above legitimate results for popular software
- YouTube and forum posts with "tutorial" videos containing infected download links in descriptions
What It Does On Your Machine
Upon execution, MetaStealer works quickly to harvest as much sensitive data as possible before the user realizes something is wrong. The malware targets web browsers first, extracting saved passwords, cookies (session tokens that can bypass two-factor authentication for active sessions), autofill data, and browsing history. It scans for dozens of browsers including Chrome, Firefox, Edge, Opera, Brave, and their derivatives. The stolen browser data gives attackers immediate access to your email, banking, social media, and shopping accounts.
Beyond browsers, MetaStealer inventories your system for cryptocurrency wallet applications and browser extensions. It specifically targets wallet files and configuration data for Bitcoin, Ethereum, Litecoin, Monero, and numerous other cryptocurrencies. If you use desktop wallet applications like Exodus, Electrum, or Atomic Wallet, the stealer copies wallet files that may allow attackers to drain your holdings if they can crack the wallet password or if you didn't use one. The malware also collects system fingerprinting data including hardware specifications, installed software lists, running processes, and IP address information—intelligence that can be sold to other criminals or used to tailor future attacks specifically to your system.
MetaStealer typically operates as a "grab-and-go" threat. Unlike ransomware or remote access trojans that establish persistent footholds, this stealer runs once, collects everything it can, transmits the data bundle to its command-and-control server, and may then delete itself. This approach makes detection more difficult because the malicious executable might not be present by the time you notice suspicious account activity. The damage is done during that first execution—your credentials are already in criminal hands.
Manual Removal — Step by Step
Disconnect from the Internet Immediately
Before doing anything else, disconnect your computer from all networks. Unplug your Ethernet cable or disable Wi-Fi. This prevents the malware from transmitting any additional data and stops attackers from using already-stolen session cookies to access your accounts while you work on removal.
Boot into Safe Mode with Networking
Restart your computer and boot into Safe Mode with Networking. On Windows 10/11, hold Shift while clicking Restart, then navigate to Troubleshoot > Advanced options > Startup Settings > Restart, then press 5 or F5 for Safe Mode with Networking. This loads Windows with minimal drivers and prevents most malware from auto-starting.
Run a Full Scan with Updated Security Software
Update your antivirus software (Windows Defender works if you don't have third-party protection) and run a full system scan. MetaStealer is detected by most modern antivirus engines, though detection names vary. Let the scan complete even if it takes several hours—rushed scans miss threats.
Use a Dedicated Anti-Malware Scanner
Download Malwarebytes (free trial available) on a clean computer, transfer it via USB drive, and install it in Safe Mode. Run a Threat Scan as a second opinion. Malwarebytes often catches stealer variants that traditional antivirus misses, and it's specifically tuned to detect info-stealer behavior patterns.
Check Startup Programs and Scheduled Tasks
Open Task Manager (Ctrl+Shift+Esc), go to the Startup tab, and look for unfamiliar entries. Disable anything suspicious. Then open Task Scheduler (search for it in Start menu) and review scheduled tasks for anything you don't recognize. MetaStealer variants sometimes create persistence mechanisms despite the typical "run-once" pattern.
Manually Check Critical Browser Data Folders
Navigate to C:\Users\[your username]\AppData\Local\ and AppData\Roaming\ and inspect folders for your browsers (Chrome, Firefox, Edge). Look for recently modified files in dates matching when you suspect infection occurred. Delete any suspicious executables or DLL files, but be cautious—deleting the wrong browser files can break the application.
Clear All Browser Data and Sign Out Everywhere
Once scans are clean, open each browser and clear all browsing data (history, cookies, cached files, saved passwords—everything) from the beginning of time. Most browsers also have a "sign out of all devices" option in account security settings. Use it. This invalidates stolen session cookies so attackers can't use them even if they captured them.
Change All Passwords from a Clean Device
Using a smartphone, tablet, or another confirmed-clean computer, change passwords for every important account: email, banking, social media, shopping sites, work accounts—everything. Enable two-factor authentication (2FA) on every service that offers it. Do NOT change passwords from the infected computer, even after cleaning, until you're certain it's secure.
Monitor Financial Accounts and Enable Alerts
Check your bank and credit card statements for unauthorized transactions. Set up alerts for any purchase over $1 or any login from a new device. If you use cryptocurrency wallets, check balances immediately and consider transferring funds to new wallets with fresh keys if you have any doubt about compromise.
Consider a Complete System Reinstall for Critical Cases
If the infected computer handles sensitive business data, financial information, or you simply want absolute certainty, the safest approach is backing up personal files (documents, photos—not applications or system files) to external storage, then performing a clean Windows reinstall. This is the only way to guarantee complete removal of sophisticated malware variants.
Prevention
- Never download software from unofficial sources. Pirated software, game cracks, and "free" versions of paid tools are the number one delivery method for info-stealers. If you can't afford a program, look for legitimate free alternatives rather than cracks.
- Keep Windows and all applications updated. Enable automatic updates for Windows, browsers, Java, Adobe products, and everything else. Many infections succeed because they exploit vulnerabilities that have been patched for months or years.
- Use unique, strong passwords for every account. A password manager like Bitwarden (free) or 1Password makes this practical. When MetaStealer captures passwords, unique credentials mean only one account is compromised instead of dozens that share the same password.
- Enable two-factor authentication everywhere possible. Authenticator apps (Google Authenticator, Microsoft Authenticator, Authy) provide much stronger protection than SMS codes. Even if attackers steal your password, they can't log in without the second factor.
- Don't store cryptocurrency wallet passwords in browsers. Write them down physically and store them securely, or use a hardware wallet for significant holdings. Browser-saved passwords are among the easiest targets for info-stealers.
- Be skeptical of email attachments and links. If you weren't expecting an invoice, shipping notification, or document, don't open it. Verify with the supposed sender through a separate communication channel before clicking or downloading anything.
- Run reputable antivirus software and keep it updated. Windows Defender is adequate for most users if kept current. Third-party options like Bitdefender, ESET, or Kaspersky offer additional layers. Free antivirus is better than none, but avoid obscure "security" programs that are themselves malware.
- Regularly back up important data to offline storage. While info-stealers don't destroy data like ransomware does, infections often necessitate complete system reinstalls. External hard drives or cloud backups ensure you won't lose irreplaceable files during cleanup.
